So - you think your 50cc ped is fast ?

[Lone-Wolf]

Wotcha.

Now THIS is what you call a fast 50cc. Acceleration ain't all that good, but it don't half get a wriggle on

Sorry, but I have had a fiat punto drive next to me, and my GPR does 234mph up a hill with a headwind.

Wonder if he took a paper to read while it was accelerating?

New video of Buddfab. Awesome

It shifts when it hits the powerband.

powerband must be narrow as fuck to produce that sort of power

when the reeds open ? the open and close at every stroke of a piston , your thinking about a powervalve mate

[Hutchysrs50]

[chillpill]

please do .....

a reed valve is a valve that lets the fuel air mixture enter the crankcase

as the piston goes up crankcase volume increases and pressure decreases this pressure gradient cause fuel/air mixture to be drawn in from the carb into the crankcase rushing through the reed block and forcing the reeds open, when the pressure is equalised the reeeds snap shut again, the mixture cannot go back through because of the shape of the reed block

[Hutchysrs50]

thanks for the info... although i know all of that....

What i dont know is, why do the revs increase and the power increase when it hits 7k+ revs?

warp drive powervavle?

the extreme timing and size of the ports on that barrel would cause it to have a very narrow powerband , not too clued up on porting to explain it any more but its something i want to get into

[Hutchysrs50]

oh well.. Good luck with that.

i took a drill bit to my reed block and manifold
